36424 - BUSH CASE FLANGED TYPE (TH400/4L80E)

# 36424

BUSH CASE FLANGED TYPE (TH400/4L80E)

No walk out type bush

Symptoms:

Bushing walks out
Case damage
Output shaft & case damage
Metal contamination

Cause:
Lack of flange or stop surface on the case bushing.

Correction:
Sonnax no walk-out case bushings are flanged to prevent movement in either direction.

The OE case bushing in vehicles with a GM THM-400, 4L80-E and 4L85-E transmissions tends to walk out of the housing bore. This leaves the output shaft unsupported, ruins the governor gear and can cause case damage. The no-walk flange feature of the Sonnax case bushing 34006-SP is specially designed to keep the bushing in the case bore.

High-quality bronze
Flange on the transmission case side prevents bushing from walking completely through the bore
Flange accurately locates and helps retain the selective washer
Machined oil grooves allow for a supply of lubricating oil to enter the extension housing as well as the transmission case.

Note:
The housing bore should measure between 2.1285"/2.1295" in diameter for an ideal fit. When damage to the case is so severe that bore diameter is larger than 2.129", use Sonnax oversized case bushing. See instructions for details.
